Hamburger
Explanation: I ate a hamburger yesterday and methane came out my butt
You need 158.70 grams of Fe2O3 to produce 111 grams of Fe. This is calculated by using the molar masses and stoichiometric relationship of the two compounds.
Solution:
MM Fe = 55.845 g/mol
MM Fe2O3 = 159.69 g/mol
Fe: Fe2O3 = 2 mol:1 mol
11 g FE (1 mol Fe/55.845 g Fe) (1 mol Fe2O3/2 mol Fe) (159.69 g Fe2O3 / 1 mole Fe2O3) = 158.70 grams Fe2O3
A lava lamp is basically a hot liquid with chunks of the same hardend liquid and they rotate when they are heated
Cl is stable as a diatomic molecule where the 2 Cl atoms are held together by a covalent bond
molar mass of the diatomic molecule is 70.9 g/mol
therefore 70.9 g of Cl₂ is - 1 mol
then 140 g of Cl₂ is - 1/70.9 x 140 = 1.97 mol
there are 1.97 mol of Cl₂ present
Answer:
The boiling point of water, or any liquid, varies according to the surrounding atmospheric pressure. ... With that much less pressure, you don't need to apply as much heat to push vapor pressure beyond the surrounding atmospheric pressure – in other words, water boils at a lower temperature.
